In humans there are 6 common sex karyotypes: XX, XY, XXY, XXXY, & XYYY. & there are 4 rare sex karyotypes: XO, XO/XX mosaicism, XY/XXY mosacism, XXY/XXXY/XXXXY mosaicism.Dec 2, 2020
In humans, the Y chromosome carries a gene (SRY) that encodes a testes-determining factor. If an individual has a Y chromosome with a functional SRY gene, they will develop testes and therefore will be biologically male. Absent a Y chromosome and functional SRY gene (unless the SRY gene has been transposed to an X chromosome), an embryo will develop ovaries and will therefore be biologically female. What’s important to note is that the presence of a Y chromosome, or two, or three, etc., all result in the development of testes and therefore these individuals are biologically male. Likewise, individuals with additional or fewer X chromosomes, in the absence of a Y, all develop ovaries and are therefore biologically female.
